To all whom it may concern:

Be it known that we, WILBUR E. BARNES and .MELVIN E. Bannns, citizens ofthe United States, and residents of Newark, county of Essex, and Stateof New Jersey, have invented certain new and useful limprovements inLooms, of which the follow ing is a specification, i

This invention relates to an improved loom, and is designed moreparticularly as a small loom operated by hand and adapted for home andschool use for the weaving of scarfs, table runners, small rugs andsimilar articles, the loom being designed to be com pact and to be.simply operated.

The invention relates to a loom of this kind in which some of the warpthreads are substantially fixed while other of the warp threads areadapted to be shifted above and below the fixed warp threads so as toalternately form thevshed above and below such fixed strand. Such fixedwarp strands e preferably each alternate strand, and the mechanism formoving such movable warp strands is a single heddle which is operated inone direction by a treadle, preferably a foot treadle, and in the otherdirection by a springer springs disposed so as not to interfere with theoperation of the loom but still occupy a position that makes themovement of the heddle even and positive.

The invention further provides for a loom i of this kind in which theheddle operating device, which permits its manual operation such as thetreadle, is so disposed as to give suflicient power to make theoperation of the loom easy and to act as stop for the up ward movementof the heddle, which upward movement is caused by the springs aforesaid.

The invention further consists of details of construction which arefully set forth hereinafter and are finally embodied in the clauses ofthe claim.

In the drawing, Figure 1 is a top View, broken awayso as to condense theview, of our improved loom. Fig. 2 is a side view partly broken away toshow-theheddle operating means to better advantage. Fig. 3 is a frontview of the loom shown in Figs. 1 and 2, and Figs. d and 5 are a sectionand broken end view, respectively, showing the means of attaching thewarp threads to the beams.

The loom comprises two side structures comprising the legs or uprights10 arranged on each end of each side so as to form corner posts, thesebeing connected on each side by longitudinally arranged side frames 11,which are preferably eacn made of one piece, although they can be madein a different manner, the side frames 11 being attached to the legs 10and acting to support the upper part of he loom mechanism, beingsuitably cut away at 12 to permit the passage of the shuttle into theshed. The side frame on each side is raised as at 13 to give the properamount of bearing for the heddle. The side frames act bearings forthebeams, the guide roll 1% and the breast-beam 15 acting to support thewarp threads at a proper height andbeing provided with suitable let-edand take-up beams 16 and 17, respectively, each of which latter can beprovided with ratchets 18 and 1E) resped tively, a d having therectangular ends 20 and 21 for the reception of suitably formed part 22of the handle 23, this detach able handle being used for turning the letoff beam 16 and the take-up beam 17 when the weaver finds it necessary,and the ratchet-s 18 and 19 serving to hold the let-off and take-upbeams against rotation when desired. The warp threads are arranged sothat some of the threads are substantially fixed in position, forinstance, each alternate warp thread passes directly from the guide rollA to the breast-beam 15,'as at 2%. The remainder of the warp threadspass, as shown at 25, through the heddle frame 26, the heddle framehaving the required number of hcddles 27 with the proper mails 28 whichare attached to the lathe of the heddle frame. The side pieces 30 of theheddle frame slide in the grooves 31 in the side frames 11, the grooves31 not extending to the bottom of the side frames so that they formstops at their lower ends 32 to limit the down ard movement of theheddle. The heddle frame is arranged so that its lower lath andupper-lath stop on the respective upward and downward movements of theheddle frame as not to disturb what we will call in this specification,the fixedwarp threads 24-, so that when the heddle frame is throwneither upward or downward it forms a shed either above or below thefixed warp threads 24, these sheds being illustrated at 38. To provide asmooth and easy operation of the heddle frame the strands 3d areattached near the outer ends of the lower lath 29 of the heddle frame,or at any other suitable point near the sides strands 34 are fastened tothe rear leaf 35 as near'to the swinging end as desirable so as y togive the heddle frame the proper amount of movement.

The rear leaf 35 and the front leaf 39 of the treadle are properlychamfered as at 42 so that when they are in their upward positions shownin full lines in Fig. 2 they act as a stop to limit the upward movementof the heddle frame, the heddle frame being moved upward by springsWhenthe foot treadle is released. These springs 43 are arranged on eachside and are fastened at their bottom ends as at 44 tothe-rear postsQlOon each side of the loom frame and are extended over a suitablesupporting rod 45 which extends from one side to the other, the freeends 46 of the springs 43 bein arran ed to ress a ainst the lower b O Couter edges of the heddle frame so as to given. pressure on each sidenear the end of the heddle and thus equalize its movement and insure itagainst binding in the machine frame. The arrangement of the springs issuch as to provide a minimum of interfer. encewith the operation of thelo0m,'the

springs being installed so that they have a substantially long free endand the pressure does not materially increase as the spring is flexed inlowering the heddle. This makes the loom easy to use. 7

The reed frame consistsof two side strips 47 which are hinged at 48tothelongitudinal braces 49 and can be swung forward and backward. frameisprovided with suitable heddles 50 through which the warp strands pass,as is usual in looms. The warp threads are fastened to the take-up beamsby securinga strip of canvas or the like, as 51, to the beams, one ofwhieh,l7, is shown in Figs. 4 and5. The canvas strip may be attached bysuitable tacks or nails 52 and may have suitable gromets or eyelets 53,and the warp Copies this patent may be obtained fer The upper part ofthe heddle d February, 1916.

threads are knotted as at 54 into these .gromets and thus held against-being -released, as will be evident." On the operation of the loom theparts are normally in the position shown in the drawing, forming theupper shed 33, and fio the weft is passed through the shed in'anydesired manner either'by a shuttle or other means, and then the treadle39 pressed.

This pulls the heddleframe down, over com "1 ing the pressure of thespring 46,and a lower shed is formed, that is a shed beneath the fixedwarp threads 24, and the weft is: again passed through usually iii-theoppo site direction fromthe' first-mentioned passage, and then when thepressure isremoved from the treadle the original position is assumed andby a repetition of these movements and the formation of'the alternate"sheds the weft threads are inserted. 'W'hen necessary, the fillin'gvispressed into place by means of 'th'ebeater or "reed' frame 47 which,when pulled forward, causes the product of the loom.
